Assume you do the following in a local Notebook:
Visit also:
store = PersistentSymbol["store", PersistenceLocation["Cloud"]];
EntityRegister[store]
Then elsewhere (such as via a Cloud Notebook) you make changes to the store then push them back to the CloudObject (which changes you can view by loading the CloudObject page).
If you execute the following then inspect an Entity that was changed via elsewhere its values will not have changed:
EntityUnregister["type"];
store = PersistentSymbol["type", PersistenceLocation["Cloud"]];
EntityRegister[store]
There is some kind of caching going on. Maybe there is some "official" way of refreshing it, but one easy workaround is to use CloudGet instead and access the un-held EntityStore the pulled expression contains as [[1]][[1]]:
EntityUnregister["type"];
store$get = CloudGet["https://www.wolframcloud.com/env/username/Persistence/store"][[1]][[1]];
EntityRegister[store$get]
